The story of the X-wing.

The Incom T-65 X-Wing Starfighter is the the frontline fighter of the Rebel Alliance and later the New Republic.
The Rebel Alliance's X-wing starfighter was one of the most advanced fighters of its day when Luke Skywalker flew it into battle against the first Death Star. Many fighters have come along which are faster and more heavily armed, but the X-wing has been assured its place in history because of its role in that the Alliance victory.
Yet it's a miracle that the Alliance has the fighter at all. The T-65 X-wing was the last starfighter design produced by Incom Corporation before its seizure by the Empire. When the X-wing was in its final design stages, ISB (Imperial Security Bureau) agents began to suspect that members of Incom's staff might have sympathies for the Rebel Alliance. A Rebel commando team helped Incom's senior design staff defect to the Alliance; the designers took with them all the plans and prototypes of the X-wing.
The X-wing takes its name from its pair of double-layered wings, deployed into the familiar X formation for combat. During normal sublight space flight, the double-layered wings are closed, giving the fighter the appearance of having only two wings. Each wingtip has a high-powered Taim & Bak KX9 laser cannon. The four cannons can be fired simultaneously, in sequence, or in pairs. A pair of Krupx MG7 proton-torpedo are located midway up the main spaceframe. Each carries a magazine of three torpedoes; those specialized weapons allowed the Alliance to destroy the Death Star. The battle station had thermal exhaust vents, unshielded against particle weapons such as proton torpedoes, meaning that a well-placed shot could cause a chain reaction to destroy the Death Star.

The X-wing is a small single-pilot fighter. An industrial Automaton R2 astromech droid, housed in a snug droid socket behind the pilot, handles many in-flight operations, such as damage control, astrogation jumps, and flight performance adjustment.
The X-wing's controls are reminiscent of those of t-16 airspeeders and other common "sport" vehicles found on frontier worlds. Bush pilots train their refleces on such vehicles and easily make the adjustment to the X-wing's familiar controls.
Thw X-wing is known for its durability, with a reinforced titanium-alloy hull and high-powered Chempat shield generators. It is a forgiving fighter and normally can take minor hits without a serious loss of performace. It has a full ejection system, and Alliance pilots have fully sealing suits and helmets.
Like the older Alliance Y-wings, X-wings have a hyper-drive for travel to other systems (the specific drive is an Incom GBk-585 unit). The R2 astromech unit can store up to ten sets of jump coordinates and handles all astrogation duties, because the X-wing lacks a navigation computer.

The T-65 X wing is the most known starfighter in the rebel alliance. Has four wings (in x formation) with laser cannons on each wing. It can fire proton torpedoes, has deflector sheilds, and can carry a R2 unit for navigation and repair. The X Wing can go faster if the wings close up. Luke Skywalker used this vehicle to destroy the Death Star by firing 2 torpedoes into the Death Star's thermal exhaust port.

Pilots of Rogue Squadron favored using the multi-role X-wing fighter, flying it as often as they could on most missions; they only employed other craft for highly specialized missions, such as missions that required ion cannons. The X-wing was so predominantly flown by Rebel and New Republic forces that it became a symbol of their faction, much like the TIE fighter and Star Destroyer were symbols of the Galactic Empire.
Thanks to continued upgrades to the basic design and improved tactics, the X-wing series remained one of the galaxy's predominant multi-role starfighters for over 40 years.
